51Shogi is an independent English-language learning site for international players. It connects rules, diagrams, opening plans, tactical patterns, endgames, and game review in one learning path.
What the Site Promises
- English-first explanations with specialist terms defined on first use.
- One coordinate system: Sente at the bottom, files 9-1, ranks a-i.
- A clear distinction between official rules, platform rules, and strategic recommendations.
- Corrections made in place so the same public URL remains useful.
Editorial Method
Rules are checked against current primary sources, including the Japan Shogi Association playing rules. Position-specific claims are checked against the displayed board, side to move, pieces in hand, and legal routes from the starting position. Strategy is described with its conditions rather than as a universal command.
Translation Standard
English names come first. Romanized terms such as sente, gote, joseki, tesuji, and shuban are introduced only when they help readers use books, broadcasts, game servers, or analysis tools. The public site does not require Japanese script.
Independence and Review
51Shogi is not affiliated with the Japan Shogi Association or a commercial shogi platform. Content is published under the 51Shogi editorial name. The site does not claim professional-player review unless a real reviewer is named with permission.
AI-Assisted Editing
AI tools may assist with drafting, translation checks, code, or quality-control searches. AI output is not treated as a source. Public lessons are edited against the displayed position, the site’s terminology standard, and cited primary references before publication. Unsupported claims and invented reviewer credentials are not acceptable.
Update Policy
Rules and platform-sensitive guidance are reviewed when an authoritative source changes. Evergreen lessons are reviewed when a reader reports an issue, when a linked source changes, or when a site-wide audit finds inconsistent terminology, coordinates, accessibility, or interaction behavior. Material changes retain the public URL and update the review record.
Corrections
To report a rule, coordinate, diagram, accessibility, or translation problem, use the Contact page and include the article URL and exact passage. Substantiated corrections are applied to the existing article and recorded in its review note.
